25+ Best free operating systems for PC, Laptop, Netbook 2019

21. SteamOS

SteamOS Valve’s SteamOS is currently in beta. Technically, Steam OS is just a Linux distribution and includes much of the standard Linux software.

However, SteamOS is positioning itself as a new operating system for PC games. The old Linux desktop is there below, but the computer starts with a Steam interface designed for living rooms.

In 2015, you can buy PCs that come with SteamOS pre-installed, known as Steam Machines. Valve will help you install SteamOS on any PC that you like.

22. eComStation

eComStationOS / 2 was an operating system originally created by Microsoft and IBM. IBM continued with the development after Microsoft left it and OS / 2 competed with MS-DOS and the original versions of Windows.

Microsoft eventually won, but there are still old ATMs, PCs and other systems that use OS / 2. IBM once marketed this operating system as OS / 2 Warp, so you can find it with that name.

IBM no longer develops OS / 2, but a company called Serenity Systems has the rights to continue distributing it. They call their eComStation operating system. It is based on IBM OS / 2 and adds applications, drivers and other additional improvements.

This is the only operating system paid on this list, apart from Mac OS X. You can still download a free demo CD to verify it.

24. Debian

DebianThis is a free open source operating system similar to Unix, which is derived from the Debian Project launched in 1993 by Ian Murdock.

It is one of the first operating systems based on the Linux kernel and FreeBSD. The stable version 1.1, launched in June 1996, is known as the most popular edition for PC and network servers.

Debian provides access to online repositories of more than 51,000 packages, all of which include free software. It is fully developed and distributed following the principles of the GNU Project.

What is an operating system and how to choose the best one?

The operating systems are computer programs. An operating system is the first piece of software that the computer executes when you turn on the machine.

The operating system loads into memory and begins to manage the resources available on the computer. Then it provides those resources to other applications that the user wants to run. Typical services provided by an operating system include:

A task scheduler: the task scheduler can assign the execution of the CPU to a series of different tasks. Some of these tasks are the different applications that the user is running and others are tasks of the operating system.

The task scheduler is the part of the operating system that allows you to print a document from your word processor in a window while you are downloading a file in another window and recalculating a spreadsheet in a third window.

A memory manager: the memory manager controls the system RAM and usually creates a larger virtual memory space by using a file on the hard disk.

A disk manager: the disk administrator creates and maintains the directories and files on the disk. When you request a file, the disk administrator brings it from the disk.

A network administrator: the network administrator controls all the data that moves between the computer and the network.

Other I / O service administrator: the operating system manages the keyboard, the mouse, the video screen, the printers, etc.

Security Administrator: the operating system maintains the security of the information in the files of the computer and controls who can access the computer.

An operating system usually also provides the default user interface for the system. The standard “appearance” of Windows includes the Start button, the taskbar, etc.

The Mac operating system provides a completely different appearance for Macintosh computers.

Linux is both a “phenomenon” and an operating system. To understand why Linux has become so popular, it’s helpful to know a little about its history.

The first version of UNIX was originally developed several decades ago and was used primarily as a research operating system in universities.

High-powered desktop workstations from companies like Sun proliferated in the 1980s and all were based on UNIX.

Several companies entered the field of workstations to compete against Sun: HP, IBM, Silicon Graphics, Apollo, etc. Unfortunately, each one had its own version of UNIX and this made it difficult to sell software.

Windows NT was Microsoft’s response to this market. NT provides the same type of functions as UNIX operating systems: security, support for multiple CPUs, large-scale memory and disk management, etc.

The entry of Microsoft into the arena of the high-end workstation created a strange dynamic. Operating systems owned by separate companies and the lack of a central authority in the UNIX world weaken UNIX, but many people have personal problems with Microsoft. Linux entered this strange landscape and attracted a lot of attention.

The Linux kernel, created by Linus Torvalds, was made available to the world free of charge. Torvalds invited others to add to the kernel as long as they kept their contributions free.

Thousands of programmers began working to improve Linux, and the operating system grew rapidly. Because it is free and runs on PC platforms, it gained a considerable audience among hardware developers very quickly. Linux has dedicated followers and attracts different types of people:

  • People who already know UNIX and want to run it on PC type hardware.
  • People who want to experiment with the principles of the operating system.
  • People who need or want great control over their operating system
  • People who have personal problems with Microsoft.

In general, Linux is more difficult to manage than something like Windows, but it offers more flexibility and configuration options.

What is the best operating system for you?

There are many options to choose from when deciding on an operating system. At the end of the day, everything comes down to what your needs are.

When putting together an office system or a corporate server, you probably do not opt ​​for Mac OS. If you are looking for a home server for personal use, there are a couple of different options to choose from. Ubuntu, Debian, Fedora and OpenSuse are excellent options.

When it comes to an operating system for your company, Microsoft Windows Server, Ubuntu Server, CentOS Server and Red Hat Enterprise Linux Server are all fantastic options to consider. Microsoft Small Business Server is an excellent option for smaller companies with less than 75 users.

For medium-sized companies, due to their scalability, Ubuntu servers: the Ubuntu operating system and the Ubuntu server are excellent.

For large companies, because most people are familiar with the system, the Windows 10 operating system is still an excellent choice.
